Swap File for low end dev servers

I have a Digital Ocean Vps, but only for hobby projects. So it has merely 512Mb memory. If you wantto run multiple applications on a small development server you can operate with more memory, just use swap files."Swap
space will allow the operating system to temporarily move data from
memory onto the disk when the amount of information in memory exceeds
the physical memory space available"Of course it will be much slower. Fortunately D.Ocean has only Ssd hard drives, so Ssd improves the situation.Here are the bash lines from a Digital Ocean article:sudo fallocate -l 1G /swapfile; sudo mkswap /swapfile; sudo swapon /swapfileCreate an empty 1Gb file; Format to swap space; Enable itThis swap file remains until the next reboot!
